UNIVERSAL CONTACT BOX WIRES.

Application filed March 21, 1921. Serial No. 454,239.

To all whom t may concern.'

Be it known that I, ERNEST GAILLEMIN, a citizen of the French Republic, and residing at 2bis Rue de PEgalit, Vincennes, Seine, France, have invented certain new and useful Improvements in or Relating to Universal Contact Boxes for Wires, of which the following is a specification, reference being had therein to the accompanying drawing.

The present invention relates to a contactk boX for flexible electric wires of that kind in which pins are used and'are adapted to pierce the covering of the wire .torinake electrical connection. The device enables a supply being obtained .in a yfew seconds in a practical, sure, and economical way along the wires generally employed, and this without the assistance of a mechanic and without displacement of the wires in fittings already set up and in a manner which will leave them intact in the event of the apparatus being removed or displaced.

The device permits of easy, rapid and economical setting up of electric lights for shop-windows, illuminations, etc., and can be applied to a number of other purposes.

The invention is clearly illustrated in the accompanying drawing, in which Figure 1 is a front view yof the apparatus with the lamp holder and wires in dotted lines.

Figure 2 is a side elevation of the device seen in Figure 1, with the lamp holder removed.

Figures 3, 4, 6, 8 and 9 show details of the various parts.

Figures 5, 7 and 10 show parts.

Figure 11 is a central vertical section through Figure 1.

Figure 12 is a vertical section at right angles to Figure 11.

Figure 13 is a perspective view showing the manner of fixing the lid to the bottompiecel or body.

Figure 14 is a plan view of the bottom part.

Like letters of reference indicate like parts in the different views.

Referring to the drawings,

details of other o designates the body part having the grooves a upon opposite sides thereof for the reception of inturned lugs p on the cover q, as seen best in Figure 12.

The body part is formed of ebonite or i other vsui-table insulating material having the spaced-apart vertical openings b and b, as seen best in Figure 11, and also with openings c and c at right angles thereto, as seen clearly in Figure 11. 1 Fitted withinlthe openings b and b are the metallic (preferably brass) parts d and df, having the vertical recesses e and e', to receive the uncovered ends 1" of the wires s, as seen in Figure 11. These ends of the wires are secured in place by means ofthe screws f and f', as seen in Figure 11. The Lipper ends of the members d and d carry 'the vertically disposed steel points or pins g, g', as seen in Figure 11, designed to engage and .pass through flexible supply wires.

The body part is provided with an aperture j to receive the bolt t provided with a nut u by which the device may be secured to any suitable support, as a wall, or an ordinary nail or screw may be used for this purpose.

The cover q is applied by sliding the same endwise on the body, with the lugs p engaging the grooves a of the body. The points g, g are thus protect-ed, and the wire by which the current is supplied is completely surrounded. This cover is provided with insulating material z', as seen in Figures 2, 5, 11 and 12, which has a notch o to receive the points g, g', and thus I not only vinsure proper insulation, but keep the wires in vposition and prevent them from movement toward the point, and thus good contact is at all times assured.

w is a forked member, the forks w of which have elongated slots wz for the reception of the bolt t in the aperture j', the arrangement being such that this forked member may slide or turn and assume almost any desired position around the bolt, as will be seen in Figure 1. The end of this forked member is provided with a screw-threaded portion a". for the attachment of a socket y. as seen in Figure 1, or any other appendage generally employed in electrical installations may be used.

Figures 1, 2, 3 and 14 show the bottom part a of metal, which is used in the event of the apparatus being fastened to a wall or other surface. 7c and 7c are two hooks or tenons on said bottom part, and Z is a stub screw slightly longer than the thickness of thel bottom. m and m are two holes serving to receive fastening screws m2, m', see Figure 1.

VFigure 13 shows the manner in which the `bottom isfastened to the cover of the apparatus. The latter is provided With a notch n Which is brought opposite one of the hooks la or c, the other edge 'of the cover being already engaged in the opposite hook; it is then possible to move the cover, the edges of which are caught between the two tenons until it is in the position desired. Before fastening the bottom to the Wall, the screw Z can be tightened so as to press hard against the center of the cover whereby rigidity is assured.'

It will be seen thata universal contact box for ieXible Wires is obtained which consists of a block equipped WithtWo points or needles adapted tol penetrate the Wires, and `a cover slidably fitted to the block which keeps the Wires in position; and that the -rapparatus can be used alone in the case of'a simple supply or alforked joint sliding and pivotingaround a fastening bolt enabling a socket for a lamp or other device to be fixed to the apparatus and to be moved to any desired positions.

lhat is claimed as new is l. An electric fitting comprising a body having slots and openings at an angle therew to,.bifurcated members fitted in said slots and carrying pins, means passed through said openings and into the bifurcations of said members to enga-ge Wires disposed in said bifurcations, and a cover slidably mounted on said body and having an insulating member.

2. An electric fitting comprising a body having slots and openings at an angle thereto, bifurcated members fitted in said slots and carrying pins, means passed through said openings and into the bifurcations of said members to engage Wires disposed in said bifurcations, and a cover slidably mounted on said body and having an insulating member having a recess to receive the ends of said pins.

In testimony whereof I affix my signature.

ERNEST GAILLEMIN.
